<H2><B>set lat|lon|lev|time</B></H2><P>
<code>set lat|lon|lev|time <i>val1 &lt;val2&gt;</i></code><p>
This set command sets one dimension of the dimension environment using
world coordinates.<p>
<H3>Usage Notes</H3><P>
When you enter dimensions in grid coordinates, they are
always converted to world coordinates. This conversion requires some
knowledge of what scaling is in use for grid to world conversions. The
scaling that is used in all cases (except one) is the scaling of the
DEFAULT FILE. The exception is when you supply a dimension expression
within a variable specification, which will be covered later. <p>
<H3>Examples</H3><P>
<ol>
<li><code>set lon -180 0</code> (sets longitude to vary from 180W to 0).
<br>

<li><code>set lat 0 90</code> (sets latitude to vary from the equator to
90N)
<br>

<li><code>set lev 500</code> (sets the level to 500mb - a fixed dimension)
<br>
</ol>
